After nearly 14 years off the air, The X-Files returned for a limited run earlier this year, to high ratings and mixed reviews. Some critics noted the awkwardness of the show having to reset and reintroduce itself after its long hiatus, a problem that Fox CEO Dana Walden says the series would not have in future episodes.

"The show was off the air for a very long time," says Walden. "They had the challenge of filling in the mythology. ... Going forward there won't be the same obligation to reset the series."
